VEC completes the construction of the A6-bidding-package-additional-category and the A8-bidding-package-traffic-safety-category work

Jul 13 2017

Noi Bai – Lao Cai expressway construction project (stage 1), operated and managed by Vietnam Expressway Corporation (VEC), is the expressway project with the largest scale up to now. The project was launched on 25/4/2009 and the entire line was put into use on 21/9/2014.

The
efficiency of the project

The emergence of Noi Bai – Lao Cai
expressway is the changing factor for the transportation system of our country,
it is also a significant incentive which fosters the socio-economic
development, reveals the tourism potential, attracts the foreign investment,
all of which resulted in positive changes in the life of the people in the
Northwest region.

Circulation on Noi Bai – Lao Cai
expressway has reduced the travelling time from Ha Noi to Yen Bai, Lao Cai,
Tuyen Quang, Lai Chau, Ha Giang by 1/3, saving 20-30% cost. It is estimated
that this expressway would benefit our society with 1.800 billion dong in a
year’s time.

Other than an apparent economical
efficiency, the exploitation of Noi Bai – Lao Cai expressway has also decreased
the traffic density, contributing to the diminishing traffic jams and accidents
on National road 2, National road 2B, National road 32C, National road 4E and
National road 70. Particularly after the circulation on Noi Bai – Lao Cai expressway,
96% of heavy truck and 79% of small car have switched from National road 70 to
circulate on Noi Bai – Lao Cai expressway instead; the result is the reduction
of 85% of accident on nearby provinces and 95% of fatal accident on neighboring provinces and national roads…

In order to further improve the traffic
safety, reduce traffic accident/mishap, provide customers with the best quality
services and enhance the exploitation efficiency of Noi Bai – Lao Cai
expressway construction project, Prime Minster has agreed with the request made
by the Ministry of Transport to spend a part of the excessive capital from the project
(sponsored by ADB) on necessary categories such as adding road for vehicles
from Yen Bai to Lao Cai (expanding road from 2 lanes to 4 lanes); reinforcing
the slopes; extending the underpass where expansion
from 2 lanes to 4 lanes is made; installing the guardrail plates, the
light-reflecting road studs and the shock-reducing devices throughout the line…
These additional categories mainly concentrate at the A5, A6, A7 and A8 bidding
packages with the total construction fee being around 740 billion dong.

On 03/11/2016, VEC began the
construction of the A6 bidding
package additional category and the A8 bidding package traffic safety category
(extending the scope of the A6 bidding package) of Noi Bai – Lao Cai expressway
construction project. On 30/5/2017, VEC has completed all these
categories.

*
Road expansion from 2 lanes to 4
lanes at certain parts of the line with slope being ≥4%, at curved paths which hinder the driver’s ability to
see and paths with long passing distance, consisting of 4 parts (Km160+140 – Km162+750; Km163+300 –
Km164+920; Km176+800 – Km180+970;Km187+260 – Km188 + 600) with a total
length of 9,74km, and a cross-section of 24m (covering 04 lanes for vehicle, 02 emergency stopping lanes with center
median strip, non-motorized lane and verge).

* The traffic safety system abides by the national
Standard of road signaling QCVN 41:2016/BGTVT and the standard of expressway
signboard 22TCN331-05. The center median strip is constructed from
prefabricated cement components (each
component is 3m length, 0,5m width, 0.8m height); with an anti-glare net
installed above it (2m in length and
0.50m in height each).

The quality of the A6 bidding package
and the A8-bidding-package-traffic-safety-category construction at sections: (Km160+140 – Km162+750; Km163+300 –
Km164+920; Km176+800 – Km180+970; Km187+260 – Km188 + 600) all comply with
the technical requirement, the construction and inspection standard of the
Project, which are strictly monitored by the supervision Consultant. The
fundamental Inspection Council and the Ministry Inspection Council have
evaluated the work quality to meet the requirement of the design and it
basically can be put into use.

On 15/6/2017, the Ministry of Transport
issued an official correspondence No.6494/BGTVT-CQLXD that allowed the VEC to
begin circulating the line, to temporarily exploit the extending scope of the
A6 (extension from 2 lanes to 4 lanes) and the A8 bidding package traffic safety
category (extending the scope of the A6 bidding package) of Noi Bai – Lao Cai
expressway construction project.

During the construction period of the
A6-bidding-package-additional-category and the
A8-bidding-package-traffic-safety-category work (extending the scope of the A6
bidding package) of Noi Bai – Lao Cai expressway construction project, VEC
conducted guidance for the Northern expressway project management Board and the
supervision Consultant to regularly inspect the traffic safety, the laboring
safety and the environmental sanitation enforcing work of the Contractor to
make sure it abides by the contract terms. As a result, during the 7 months of
construction, VEC was able to secure the safety of the people and the vehicles
that participate in traffic on the operating line.

VEC did also modify the traffic
organizing Plan for the 4 expanded parts (from 2 lanes to 4 lanes) from the A6
bidding package additional category of the Noi Bai – Lao Cai expressway
construction project in order to uphold the traffic safety order, utilize the
best circulating potential of the line, minimize traffic jam and improve the
investment efficiency of the project.- VEC
